As I'm writing this, the rating is a 5.2, however there is not one negative review. That tells me that the low ratings are probably from people who didn't watch it, but saw scary words like "Civil, BLM, or George Floyd," and rated it a 1, because....that's what they do. Wouldn't want to risk making a white person, especially kids, feel a little discomfort by exposing them to the truth, right? They may realize how America's past created and still relies on systemic racism. Yes; if you voted for Trump or are still backing Trumpist Politicians, I'm referring to you. BTW, I'm a middle-aged white american woman.
If others had rated it fairly, I would've rated it an 8 instead of a 10. It was interesting, and for all that Mr. Crump has done, his name should be better known. I didn't know anything about him and I think the documentary could've done a better job of pointed out the overall significance of the court cases he was involved with. Perhaps they realized that their target audience would understand the context of events, as I did. It's also a possibility that he had some influence on the the documentary and if he's as humble as how he appeared, he may have wanted his accomplishments downplayed.
